I tried to get a Virgin Mobile Broadband2Go USB modem ( Novatel MC760) to connect without success when using LMDE as a Live DVD.

Odd because it shows up in Network Manager, allows the setup wizard to run, and tries to make a connection. It gets as far as the connection icon being lit up with the two small green balls, but that is it, no connection is made.

If you click to disconnect it in Network Manager, it displays a message stating it was disconnected.

Well, it is not the USB Modem that is having the problem while using LMDE as a Live DVD.

I connected to the Internet via Ethernet cable and did a "sudo apt-get install wvdial" to install wvdial. With it installed, I copied over a "wvdial.conf" file that I use on older distros that don't have the latest Network Manager (i.e. Ubuntu 8.04).

From a terminal window did the command "sudo pon.wvdial" and it made the connection. In fact, that is what I am using right now to post this reply.

I am running Mint 10. I am having a problem getting my Samsung Vibrant to be used as a USB Modem. I have tried wvdial, gnome-ppp, and it says please enter password. The plan that I am on does not require a username or password. I have read in many posts that the Broadcom Wireless Chipset does some crazy things with the kernel; I used the Broadcom STA drivers, because the original Broadcom drivers will not keep a connection alive. At one point in the LiveCD I had the mobile working. I did the following: Installed the Broadcom drivers, uninstalled the BC drivers, installed the BC STA drivers, setup my Mobile Broadband connection and voila! It worked! Well, after I did some updates and tested it out it no longer worked anymore. I re-installed Mint 10 did the exact same steps as above and I could not replicate the success this time. Now I am turning to the forums. Thank you for your time.
